WATER-HEATER. j

4Be it known thatI, HERBERT S. HUM- THREY, a citizen of the UnitedStates, residing at lthe city of Kalamazoo, county of Kalama- Zoo, Stateof Michigan, have invented certain new and useful Improvements in Water#Heaters, of which the following is a specification. y

This invention relates' to improvements in water-heaters.

It relates particularly to the `class of water-heaters known asinstantaneousf such as is shown and described'in Letters. Patent ofAlfred H. Humphrey, No. 704,043, dated July 8, 1902, and it is animprovement thereon and in some respects a modification thereof.

The objects of this invention are, first, to

providey an improved water-heater which issimple and compact instructure, of largecapacity, andeconomical to use;l second, to

'provide an improved water-heater to which the water is 4so deliveredand vdistributed as to be brought into such `Contact with the heated airor gases arising from the burners as to quickly absorb the heattherefrom.

j Further objects and objects relating to structural details willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the followingspeciiication.

specification, in which-.-

The invention is clearly defined, and pointed out in the claims. 'y v Astructure embodying the features of my invention is clearly illustratedin the accome panying drawings, forming a part of this .of my improvedwater-heater, the burners and the gas and water ipes being shown in Fig.2 is ap an view of the u per y tail view of the perforatedbaffle-plates.

` In the drawings similarletters of reference refer to similar partsthroughout the several views.

` vReferring to the drawings, I provide an outer casing A, which ispreferably cylindrical in form. This. casing rests upon a suitable base,as A', which is preferably provided with a bracket at one side, as a, byv which itmay be securedvto the wall or to any vPatented. Dec. 25, 1906.

other suitable support. It may of course be arranged to rest upon itsown base. The casing A is provided with a flue a at the top for theescape of the gases of combustion.

In the lower part of the casing A suitable 'y burners, as B, arearranged. These burners are connected by the pipe B/ to a suitablegas-supply.

It is evident that other meanslmight be employed for delivering heatedair or gases to the base of thel casing, although I prefer to arrangethe gas-burners therein as shown in the' drawings.

Arranged above the burners B is an openended conical tube, as G. Thistube is preferably spirallyl corrugated, as is clearly Illustrated inthe drawings. The base of the tube G is adapted to iitthe walls of thecasing A,-

land issecured thereto, thereby forming 4a water-receptacle for theheated water betweenit and-the walls of the casing. A delivery-faucet,as H, is provided for this receptacle. y

" An inverted conical'or funnel shaped plate F, having a central openingthrough which the upper end of the tube G is arranged, is provided. The'periphery of thisvplate fits the walls of the casing and is securedthereto'.

A water-deliveryk pipe C is arranged centrally in the casing through thetube G. This pipe is provided with a spraying-head c at its upper end.vThe water-delivery ipe C is provided with a suitable stop coc or valveC. i

Above the' upper open end of the tube 'G is av deiiector-plate E. Thisdeilector-plate E prevents the water from above entering the tube G andalso spreads out the heatedair -Figure l 1s a detail vertical sectionalview` or gases delivered from the upper end of the tube G. The plate Eis preferably supported on the water-delivery pipe C. Above thisdeflector-plate E are perforated bafiie-plates D one of which isarranged above the spraying-headl c andthe other below it. These fperforated b alaplates are conical in form and are arrangedinl aninverted position.`

They extend completely Aacross the casing A, forming lartitions therein,as clearly appears from t e drawings.

In operation the gas and water are preferably turned on simultaneously.The vwa-r ter is delivered by the sprinkler-head c to the under side ofthe upper baffle-plate and to .l evenly delivered to the under side ofthe I water practically absorbs all the heat thereof. 1 The water Iofvery large capacity. The parts are so arthe upper side'of the lowerbaflie-plate. The i sprinkler-head is preferably arranged so that t egreater portion of the water is delivered to the under side of the upperbaie-plate and flows or drops therefrom to the lower baffle-plate. ThesebafIle-plates are conical in form, so that the tendency of the water isto, flow down the same, and in doing so seal, or practically seal, theperforations therein. The heated air and gases of combustion pass upthrough the cone G and impinge against the under side of thedeflector-plate E by which they are spread, so that they are quite lowerbaflle-plate, through theperforations of which they pass, breakingthrough the films of water over the perforations, coming thereby inclose contact therewith, so that the waterreadily takes up the heattherefrom." The heated air and gases pass `on through the space betweenthe baffle-plates in which the water is being delivered to the plates ina spray by the sprinkler-head and through the perforations in the upperbaffleplate and are carried off by the flue a. The water and the heatedair or gas are thus brought so thoroughly into contact that the passingdown to the deflector plate E, which has become heated, absorbs moreheat. The water is delivered by the deflector-plate E to the plate F, bywhich it is delivered onto the tube G. This tube or cone G is alsoheated, so that by the time the water reaches the base of the tube it isthoroughly heated. The spiral corrugations ofthe tube G somewhat retardthe ow of water down the same and also retard the upward passage of theheated air and gases, so that it adds to the effectiveness of theheater, although satisfactory results may be secured if thesecorrugations are omitted. v By thus arranging the parts I am enabled toutilize a maximum of heat units generated by the burner. The heater isvery compact and simple and economical to produce and is ranged thatthey are very durable, and the structure is not liable to get out ofrepair or become clogged by use.

I have illustrated my improved waterheater in the form preferred by meon account of its simplicity and durability and economy in use, althoughI am aware that the structural details may be varied without departingfrom my invention.
